Description
BCAR3 Antibody detects endogenous levels of BCAR3. A ubiquitously expressed regulator of R-Ras activity that has been implicated in breast cancer. A GDP exchange factor whose overexpression confers antiestrogen resistance, activates Rac, PAK1, and the cyclin D1. Can accelerate the degradation of IRS-1, thus regulating signaling through the insulin receptor. When overexpressed, it confers anti-estrogen resistance in breast cancer cell lines. May also be regulated by cellular adhesion to extracellular matrix proteins. Up-regulated by interleukin-1-alpha and TNF-beta in thymus cortical reticular cell lines (mouse).Two alternatively spliced human isoforms have been described.
